This ink is only meant to be used with our Isograph line of pens and is not suitable for non-isograph technical pens. **Q: Does this ink work with alcohol markers?** A: If you're asking if alcohol dissolves (smears) this ink, no, not in my experience. I use the Isograph pens (with this ink) for my marker drawings with no problem at all. I also use it to line my watercolor stuff, also no smearing. **Q: Can i use this ink with a rapidograph pen or only rotring isograph pen?** A: Please be advised that only rOtring Isograph pens have refillable ink reservoirs ideal for drawers using bottle inks. The rOtring Rapidograph pens are compatible with rOtring 's unique capillary cartridges exclusively. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent and Fast delivery *by P***A on February 28, 2026* Excellent ### ⭐⭐⭐⭐⭐ Just as described *by T***R on December 20, 2025* Quality ink just as explained ### ⭐⭐⭐⭐⭐ High Quality *by L***R on June 10, 2025* I bought this ink to use in my Isograph pens. The shape and fine tip makes the ink easy to load into the pens and appears to be very water resistant, if not waterproof. It flows well and when I want to clean out a pen, the process goes well. ## Frequently Bought Together - rOtring Isograph Technical Drawing Pen, Liquid Ink, 23 ml, Black - Rotring Isograph Technical Drawing Pen, 0.35 mm - rOtring 1903394 Isograph Technical Drawing Pen, 0.1 mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/6520976-rotring-isograph-technical-drawing-pen-liquid-ink-23-ml-black](https://www.desertcart.id/products/6520976-rotring-isograph-technical-drawing-pen-liquid-ink-23-ml-black) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-10*
